WATER-GOOLED roar.

Specification of Letters :Patent. tent 25, 1919 Application filed. September 2, 1916. Serial No. 118,307.

To all whom it may concern: Be it known that I, EDWIN E. SLroK, a citizen of the United States, residing in the borough of Westmont, in the county of Cambria and State of Pennsylvania, (whose post-office address is Johnstown, vania,) have invented certain new and useful Improvements in lVater-Cooled Ports; and I do hereby declare the following to be a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and use the same.

My invention relates particularly to a water-cooled port for open hearth or other furnaces and consists of a series of pipes inclosed in a metallic casting which extends through the inner or hearth end of the arch separating the gas port from the air port.

One of the objects of my invention is to provide, at the points where the gas and air ports unite, a cooling apparatus that will absorb the excessive heat necessary in open hearth and similar furnaces, and thereby prevent the separating arch between the gas and air ports from being destroyed by the action of the high temperatures.

Another object of my invention is to so construct such apparatus pipes will not be in direct communication with the burning gases; but inclosed in a metal casting or casing that will form part of the top surface of the gas port and of sufficient thickness to carry oif the excessive heat uniformly.

A further object is to so place this cooling casting that it will reinforce and support the inner end of the arch separating the gas and air port and thereby prevent the ends of the said arch from chipping ofi or falling, if partially destroyed or broken by the heat.

Certain other objects of my invention will be apparent from the description and claims hereinafter set forth in that it may be simply and economically constructed, practical to operate and free from complications that would require frequent repairs.

Referring now to the accompanying drawings in which like letters of reference designate corresponding parts :-Figure 1 is a cross sectional elevation of an open hearth furnace on the my invention applied thereto; Fig. 2 is a cross sectional elevation of the-same furnace taken through the center thereof; Fig. 3 is a sectional view taken on the broken line III-III of Fig. 1; Fig. 4 is a plan view of P ennsylthat the coolingline I-I of Fig. 3 showing my cooling casting and pipes; Fig. 5 is a side elevation of the casting and pipes shown in Fig. 4- and Fig. 6 is a sectional end elevashown in Figs,

tion of the castingand pipes at and 5.

The airport 1 and the gas port 2 are inclined at the proper angle to cause intensely hot sheets of burning gases to be evenly distributed over the charge contained in the oval-shaped hearth 3, and being thus conducted in a downwardly direction, the burnmg gases will not be projected against the bricks of the roof 4 and of the side walls 5 above the slag line thereof, thereby preventmg the melting or destruction of this brick or refractory'material.

The flues 6 and? connect respectively the air and gas ports 1 and 2 with the regenerative chambers and'said fiues' are adapted to either admit regenerated air and gas or to conduct' the outgoing burnt gases to the regenerators whence they are conducted to the chimney.

hen the air and gas is admitted through the fines 6 and 7 and the ports 1 and 2, they willbe united at the inner end of the separating arch 8, thereby producing an intense heat that will be transmitted to the end of said arch 8. When the air and gas are being admitted at corresponding ports at the other end of the furnace, the arch 8 will besubect to a still greater heat, for in this case the intensely heated portions of the outgoin gases will be in direct communication witi the end of the arch.

In order to protect the end of arch 8 from this intense heat, cooling pipes 9, inclosed at their central portions in a casting 10, are built into the underside of the separating arch 8 at the end portion thereof. A portion of the underside of the casting 1O lies in the direct continuation of the under surface of the separating arch 8 and said charge connections 12 to boilers or to other places wherepreheated fluid may be de sired, or it may be wasted if preferred.

The casting 10 which is shown in Figs. 4, 5v and. 6, protects the water pipes 9 from the direct actions of the hot flames and not only prevents the said pipes from being It should be noted that the casting 10, in

addition to being slightly arched over the port, has flat bearing ends, which are adapted to rest upon and be supported by the brick work, the shape of these flat ends being substantially that of a brick, so that the metallic arch does not disarrange the brick courses, It should alsov be noted that the use of a number of pipes of small diameters Within the 'flat arch provides a thorough circulation of cooling water at all times within the casting; whereas in other and box-like, constructions there is no water circulation in certain localities, so that gas, steam or air accumulates and due to the absence of cooling fluid these. constructions are burned and spoiled, all of which is obviated by my plurality of small conduits of small size, each, supplied with large quantities of moving water and discharged under considerable. pressures.

Although I have shown and described my invention in considerable detail, I do not wish to be limited to the exact construction shown and described, but may use such sub stitutions, modifications, or equivalents thereof, as are embraced within thescope of any lnvention, or as pointed out in the claims.

Having thus described my invention,

what I claim and desire to secure by Lettending below and adapted to support the said separating arch andinclosing the said cooling'pipes, each pipe connected to a source of flu d supply.
